Ad Builder Text Fields Cheat Sheet
Character limits and field rules for every channel in the Ad Builder, in one place.
The Ad Builder writes one set of copy and formats it for each channel you select. Channels have different limits, so the builder truncates to the shortest one when you write once for several channels. This sheet lists the limits per channel so you can write to fit the first time.

Writing for Several Channels at Once
When you select more than one channel, the Ad Builder applies the tightest limit across everything you picked. Snapchat's 34 character headline is usually the constraint.
Write the shortest version first, then use Customize Per Channel to expand it where a channel allows more.
Meta
| Field | Limit | Notes |
|---|---|---|
| Primary Headline | 40 characters | Truncates in feed beyond this |
| Secondary Headline | 40 characters | |
| Body Text | 2,200 characters | Keep the first 125 characters strong, the rest collapses behind "See more" |
| Destination URL | Full URL required | |

| Destination URL | Full URL required |

The Ad Builder shows a live Pinterest Video Ad preview alongside the other channel previews. Check the preview before deploying to see exactly where your copy lands and whether anything truncates.
Customizing Copy Per Channel
- Write your shared copy in the main fields.
- Select Customize Per Channel.
- Open the tab for the channel you want to change.
- Edit the fields for that channel only.
- Check the live preview for each channel before deploying.
Tip: Customize the longest-limit channel last. If you start there, you will write copy that has to be cut back for everything else.
